Cuneiform cartilage

Dr Henry Knipe ◉ ◈ and Dr Clinton Nash et al.

The cuneiform cartilage is a small, paired cartilage which resides in the aryepiglottic fold. It takes the form of a club-like nodule, visible as an elevation beneath the mucosa (the cuneiform tubercle) anterosuperior to the corniculate cartilages.

History and etymology

The word cuneiform derives from the latin cuneus, meaning "wedge".
